People are more aware of the issues caused by plastic and say they are using fewer plastic bottles, a Sky Data poll reveals, as we mark a year since the beginning of the Sky Ocean Rescue campaign.

:: People are using fewer plastic bottles

In a poll taken before the start of the campaign last January, 47% said they used fewer than three disposable plastic bottles per week, with 20% using none at all.

A year on, 65% say they use fewer than three - up 18 percentage points - and 26% say they use none at all, up six points.

Over the same period, the proportion of Britons saying they use 10 or more plastic bottles per week has fallen from 16% to eight percent.

:: 9 in 10 are concerned about the impact of plastic in the ocean

Ninety percent of Britons now say they are concerned about the impact of plastics, up six percentage points since the Ocean Rescue campaign started.

Sixty-three percent say they're very concerned, up 16 points.

:: 8 in 10 support deposit return schemes

And there has been a big shift in awareness of - and support for - deposit return schemes for plastic drinks bottles; an initiative that has been given to go ahead by the Scottish government and has received backing from Tesco, Iceland and the Co-op.

The scheme would add a small deposit to the price of plastic bottles to be refunded if you return them to be recycled.

Prior to the start of the Sky Ocean Rescue campaign, 21% had heard of a deposit return scheme, and 60% supported it.

Now, 51% have heard of the idea, and 79% are in favour of implementing it.
